A lever system brake is a mechanism used to slow down or stop the movement of an object. It works by using a lever to apply a force on a brake pad, which then creates friction against a surface, causing the object to slow down or stop.
The three types of lever systems used in brakes are first-class, second-class, and third-class levers. In first-class levers, the fulcrum is located between the effort (force applied) and the load (object being moved). In second-class levers, the load is between the effort and the fulcrum. In third-class levers, the effort is between the load and the fulcrum.
The main purpose of using a lever system in brakes is to increase the amount of force applied to the brake pads. This allows for greater friction to be created, resulting in better braking performance.
The counting of forces in a lever system brake is affected by the length of the lever arm, the angle at which the force is applied, and the amount of force applied. These factors can affect the amount of force applied to the brake pads and ultimately impact the braking performance.
Lever system brakes are commonly used in various modes of transportation, such as cars, bicycles, and trains. They are also used in industrial machinery, such as cranes and forklifts, as well as in everyday objects, such as doors and scissors.
